Multi-viewpoint 3D display device

Abstract

The invention relates to a 3D display device, in particular to a multi-viewpoint 3D display device. The multi-viewpoint 3D display device comprises a 3D display device body, the 3D display device body comprises a projection screen and a projection unit, and the projection unit comprises at least three projectors for showing different viewpoint scenes. The projectors project to the projection screen which is a transmittance type diffuser screen with different projection angles, and a cylindrical surface grating is arranged on the light-emitting face of the transmittance type diffuser screen. The transmittance type diffuser screen with different projection angles is adopted for being combined with the projectors for showing different viewpoint scenes, in this way, pictures shown by the projectors for showing different scenes are projected in different directions through the transmittance type diffuser screen, and then people can enjoy different pictures from different viewpoints.

Description

technical field [0001] The present invention relates to an electronic field, in particular to a 3D display device. Background technique [0002] With the rapid development of computer technology in recent years, the research and development and application of 3D technology have gone through decades of early stage of exploration, and the maturity, perfection, ease of use, humanization, economy, etc. A huge breakthrough has been made; with the rapid popularization of computer network applications, as far as 3D applications are concerned, it has become a basic computer tool that ordinary college students can easily control, just like computer typing; 3D consumption and use, such as through 3D Games, movies, buildings, cars, mobile phones, clothing, etc. made by technology have become part of the work and life of ordinary people. [0003] In the traditional 3D display technology, the 3D display often directs the projector to the projection screen, which easily leads to the larg...

Problems solved by technology

[0003] In the traditional 3D display technology, the 3D display often directs the projector to the projection screen, which is easy to cause the existing 3D display to be relatively bulky and occupy a large area due to the requirements of the image transmission path.

In addition, traditional 3D monitors often can only enjoy the 3D effect of one viewing angle, and the 3D images watched by each viewer at different positions are the same, and can only be viewed from a single viewing angle, and cannot watch 3D images from other viewing angles.
